Rhenium Powder Description

Rhenium Powder (CAS: 7440-15-5) is a kind of silvery-gray crystal. Rhenium has high hardness, high mechanical strength, and good plasticity. It is easy to draw and roll sheets at room temperature, but it cannot withstand heat processing. The density is almost twice that of lead; the appearance is the same as platinum, silver-gray; pure rhenium is soft and has good mechanical properties.

Rhenium Powder Applications

Rhenium is used in tungsten, molybdenum alloy, or other alloy additives, such as tungsten-rhenium alloy in rod, plate, tube, sheet, and wire form as a high-temperature structural material in aerospace technology, electron tube, picture tube, and bulb hot wire, electrical contact material, High-temperature thermocouple materials, etc. Molybdenum rhenium alloy because its performance exceeds pure molybdenum and other molybdenum alloys can be used as a structural material for fusion reactors. Rhenium is a highly active catalyst, with good selectivity and maintaining its catalytic ability even after being contaminated by other substances. It is widely used in the petrochemical industry.
